Battery saver mode, reset

[tmanwell]

I just bought my Likebook Mars.
For the most part, it's exactly what I wanted, a 7"ish e-reader with Android OS allowing me to access Hoopla-Digital. Yay!

In the interest of preserving maximum battery life between charges, I typically keep it set on airplane mode and turn "battery saver" ON.

Only thing is....everytime the tablet powers off and powers back on, it comes back on with "battery saver" set to OFF.

Is there a way to set this to overcome this, or is it a matter of always remembering to re-enable battery saver every time I turn the tablet back on??

Thanks!
